Decentralized technologies (Web3, Blockchain, Distributed Ledger Technologies, Distributed Storage and Computation as IPFS) have started to disrupt multiple domains, including finance and payments, but also networks, computing, supply chain, identity management, and Artificial Intelligence with decentralized learning.

The BRAINS conference is dedicated to these advances that could make the world of networks and services more secure while enabling new distributed business models.

This year, a new DeFi track is open to both technically oriented and economics-oriented papers. We particularly welcome interdisciplinary work that combines blockchain protocols, smart contract engineering, and DeFi market design, as well as empirical and theoretical studies on crypto-economics and financial innovation.

Areas of interest include, but are not limited to:

Effective challenges for decentralized systems

Theoretical contributions to Blockchain, DLT and decentralized storage
Distributed consensus and fault tolerance solutions, including domain-specific consensus
Protocols and algorithms
Distributed ledger analytics
Trade-offs between decentralization, scalability, and security

Student Track

We encourage the submission of student papers (i.e., all authors of the paper must be MSc or PhD students) on the topics mentioned in the CFP. Student papers have to be clearly stated on the first page. The papers should follow the same guidelines as short papers (max 4 pages) and be submitted on the dedicated track for student papers.
